Explanation: Rajasthan, a state in northwestern India, is known for its diverse geography and rich cultural heritage. The question revolves around three statements related to the state's climate, historical significance, and cultural landmarks.
1. **Jaisalmer's Climate**: Jaisalmer is a city located in the western part of Rajasthan, in the heart of the Thar Desert. The climate in Jaisalmer is characterized by a desert climate, which means it experiences hot summers and mild winters. The temperature can soar up to 49°C in summer and drop to around 2°C in winter. Therefore, the statement that Jaisalmer has a very cold climate is incorrect. The desert climate is marked by extreme temperatures and low humidity, which is typical of arid regions.
2. **Kalibangan Civilization**: Kalibangan is an important archaeological site located in the Hanumangarh district of Rajasthan. It is one of the earliest known settlements of the Indus Valley Civilization, dating back to the Bronze Age. The site was discovered in 1951 and has provided valuable insights into the early urbanization and agricultural practices of the region. The excavations at Kalibangan have revealed a well-planned city with a grid pattern of streets, which is a characteristic feature of the Indus Valley Civilization. Thus, the statement that Kalibangan is a Rajasthani civilization is correct.
3. **Dilwara Temples**: The Dilwara Temples are a complex of five Jain temples located in Mount Abu, Rajasthan. These temples are renowned for their intricate marble carvings and are considered some of the finest examples of Jain architecture. The temples were built between the 11th and 13th centuries and are dedicated to the Jain Tirthankaras. The Dilwara Temples are not only significant religious sites but also important cultural landmarks in Rajasthan. Therefore, the statement that the Dilwara temple is situated in Rajasthan is correct.
In conclusion, the correct answer is (D) Only 2, 3, as the statements about Kalibangan being a Rajasthani civilization and the Dilwara temple being situated in Rajasthan are accurate, while the statement about Jaisalmer having a very cold climate is incorrect. Understanding the geography, history, and cultural landmarks of Rajasthan is crucial for comprehending the state's rich heritage and diverse landscape.
